WHY THE OX IS DIFFERENT
No need for 4-wheel drive
Four-wheel-drive systems add weight, complexity and cost to a vehicle. They also reduce ground clearance and increase tyre wear and fuel consumption. Through clever and innovative design the two-wheel-drive OX has most of the attributes of a four-wheel-drive vehicle, but without the compromises.
The OX has been specifically designed to perform as well as, or better than, a four-wheel drive vehicle, while offering low cost and durable mobility.
Ground clearance & wading capability
Covering rough ground depends less upon the number of driven wheels than the balance and the ground clearance of the vehicle. The OX is driven by two wheels, which allows a great deal more ground clearance, without the need for larger and more expensive wheels and tyres. In addition, its wide wheelbase allows it to follow the tracks of larger vehicles on unpaved roads. With wading capability in a water depth up to 1m, OX has the ability to traverse flooded terrain with ease.
The OX grips the surface over which it is travelling very effectively because it has fully independent OXGlide™ suspension on all four wheels. This also makes the vehicle much more stable over rough ground than is usually the case with off-road vehicles.
The powertrain in the OX prototypes is an ultra-reliable 2.2-litre Ford diesel unit. As technologies develop, it could be switched to an electrical or, for example, hydrogen-powered system. At present, these systems are not easily re-fuelled in the developing world.
At the heart of the vehicle is a strong but light sub-assembly that functions as a chassis and the external shell is of all-flat, extremely strong and waterproof bonded wood composite. The glass panels are also flat, which keeps initial costs low, and facilitates compact storage in the replacement-parts supply chain, thus keeping maintenance costs down.
PERFORMANCE ABOVE EXPECTATIONS
ALL TERRAIN COMPARISONS
An all-terrain vehicle should have the following features if it is going to be truly effective in coping with mud, deep sand, deep ruts, steep climbs, deep wading, highly cambered surfaces and dusty conditions:

The OX is the world’s first flat-pack vehicle. The components and sub-assemblies of the OX are tightly arranged within its own frame, with a separate transport crate housing the engine and gearbox. It takes three people approximately 5.4 hours to create the flat pack in the UK prior to shipping. The flat-packs are then transferred to a container, which can accommodate six OXs. This is effectively three times more efficient than transporting fully-assembled vehicles, of which only two would normally fit in a 40ft high-cube container.
